Problem about VIP-trimmer in dm385.(VIP get the wrong fps when startX + width>2048)
The input video format is 1080P30(clk = 74.25MHz,HSync = 33KHz,VSync = 30Hz),But with the above paremater ,captureLink can not get the right data in buffer,in only capture 15 frames per second.
If I don`t use trimmer to crop blanking region,captureLink can get 30 frames per second in buffer,with blanking region and active date.
I found that when cropStartX + cropWidth > 2048,VIP paser cannot work well.why ? anywhere have limit on this ? How can I crop 1080P active data correctly ?Thanks
2K is the maximum width supported by the VIP, so we cannot use more than 2K width.
I think in this case, your total width is more than 2048, so cropping cannot be used. You will have to capture full frame into memory and then crop blanking using some other module.

" 2K is the maximum width supported by the VIP." --- Do you mean that VIP inline sc can not handle more than 2048 width ?? what other module can do this ?
total width* height is 2200*1650 and active video is 1920*720.
We cannot use any module within VIP if width is more than even 1920. If you want to capture 2200 width, you will need to store it directly into memory withou using any internal modules, and then crop it offline by updating start buffer address..
